aggregation problem
1.The wage unit is another way to solve the aggregation problem, but the aggregation by this way represents the value relation in the money economy system rather than the gross of actual goods.
2.After analysis of inherit, logical and aggregation relationships among the objects, the object sets of problem domain, system data structure and application frameworks were designed, and the system extensibility was also discussed.
3.Abstract By setting up a network model of data aggregation and using a bit-hop metric to quantify energy costs in wireless sensor networks, we formally analyze the problem of area-based data aggregation and obtain that data aggregation will definitely be energy efficient when the relative difference between the average lengths of the two shortest paths, which are from source sensor nodes to the sink and to the aggregation node respectively, is not less than the ratio of data correlation to the number of source sensor nodes.
4.Abstract: The order reduction problem of the system state feedback and output feedback controllers is discussed according to the inclusion princip l e of linear discretetime stochastic systems.Two kinds of conditions,restrictio n and aggregation,are presented for the controller order reduction.By designing the order reduced feedback controller for a 9order system,the properties of th e reduced order controllers and all order controllers are discussed.
